Introduction to Tantalum Capacitors

Tantalum capacitors are an increasingly popular method of energy storage and are used in a variety of electronic applications. Due to their robust construction, as well as their relatively small size and excellent performance, they are often the preferred choice when selecting an energy storage device. In this article, we will explore the application field and working principle of the TWAE687M075CBEZ0700, a specific variant of tantalum capacitor.

Types of Tantalum Capacitors

In general, there are two main distinct types of tantalum capacitors. The first is the wet tantalum capacitor, which is soaked in an electrolyte such as aqueous potassium hydroxide. As the name implies, this type of capacitor is wet and can come in either an axial lead or a radial lead configuration. The second is the dry tantalum capacitor, which does not utilize an electrolyte and has a much more solid state construction. These capacitors are often preferred for more permanent or high-temperature applications, as they are more resistant to shock and vibration.

Application Field of the TWAE687M075CBEZ0700

The TWAE687M075CBEZ0700 is a wet tantalum capacitor, specifically designed for high frequency and low ESR operation. This capacitor is often used in a variety of applications, ranging from PC motherboards and cellular phones, to automotive and aerospace electronics. Due to its incredibly low ESR (Equivalent Series Resistance), it can reliably provide stable energy when dealing with high frequency energy requirements. Additionally, the TWAE687M075CBEZ0700 has an extremely small form factor, making it extremely versatile for small scale applications. The case size of this capacitor is a mere 7.3mm, allowing for the design of extremely compact and efficient pieces of machinery.

Working Principle of the TWAE687M075CBEZ0700

The TWAE687M075CBEZ0700 wet tantalum capacitor functions just like any other capacitor and is able to store energy through the use of capacitance. Capacitance is the ability of a capacitor to store electric charge and is measured in Farads. The TWAE687M075CBEZ0700 utilizes an anode consisting of tantalum, a highly reliable metal, and an electrolytic solution which serves as the capacitor’s dielectric. When an electrical current is applied to the capacitor, the stored charge will then be released. This stored charge is then stored in the capacitor’s dielectric, and when the current is removed, the charge will then slowly dissipate. This is how the capacitor is able to store and deliver energy on demand.

Conclusion

The TWAE687M075CBEZ0700 wet tantalum capacitor is an excellent choice for energy storage and handling high frequency energy requirements. Due to its small form factor and low ESR, it is able to provide reliable and stable energy to a variety of electronic applications. This article has highlighted the application field and working principle of this particular tantalum capacitor and has shown why it is an important energy storage device.
